Lang code restructure from 1c9f455c, applied to Drupal6.php
Update CRM_Utils_System_Drupal6::loadBootStrap() based on CRM_Utils_System_Drupal::loadBootStrap().
Suppress E_NOTICE errors because we can end up with corrupted JSON from Drupal init.
CRM-12869 This is a temporary fix from Eileen which prevents the over-write. However it also prevents the billing address from being saved for the payee, and requires the user to know that they need to manually replace the billing field values with the payer data. In general I do not think this record payment from a differnet contact feature  is production-ready (even though it is part of 4.3). Selecting a different payer should reload the the billing address fields with the payer info.
